Genetics of Erythropoiesis (Red Blood Cell Creation)

Written by Puya Yazdi, MD | Last updated:

SelfHacked has the strictest sourcing guidelines in the health industry and we almost exclusively link to medically peer-reviewed studies, usually on PubMed. We believe that the most accurate information is found directly in the scientific source.

We are dedicated to providing the most scientifically valid, unbiased, and comprehensive information on any given topic.

Our team comprises of trained MDs, PhDs, pharmacists, qualified scientists, and certified health and wellness specialists.

All of our content is written by scientists and people with a strong science background.

Our science team is put through the strictest vetting process in the health industry and we often reject applicants who have written articles for many of the largest health websites that are deemed trustworthy. Our science team must pass long technical science tests, difficult logical reasoning and reading comprehension tests. They are continually monitored by our internal peer-review process and if we see anyone making material science errors, we don't let them write for us again.

Our goal is to not have a single piece of inaccurate information on this website. If you feel that any of our content is inaccurate, out-of-date, or otherwise questionable, please leave a comment or contact us at [email protected]

Note that each number in parentheses [1, 2, 3, etc.] is a clickable link to peer-reviewed scientific studies. A plus sign next to the number “[1+, 2+, etc...]” means that the information is found within the full scientific study rather than the abstract.

A mutation in the JAK2 gene is the major cause of Polycythemia Vera or an increased number of red blood cells [1].

GATA 1

GATA1 (GATA binding protein 1 or globin transcription factor 1) is essential for normal red blood cell production (erythropoiesis) [2, 3, 4].

The GATA1 regulates the growth, division, and survival of immature red blood cells and platelets [5, 6, 7].

Mutations in GATA1 cause anemias and thrombocytopenia in human patients [8, 9].

Mutations in this gene are present in almost all cases of acute leukemia associated with Down’s syndrome.

ZFPM1

ZFPM1 gene (Zinc finger protein) is also known as FOG1 (friend of GATA1).

ZFPM1 plays an essential role in red blood cell production. Interaction of ZFPM1 with GATA1 is essential for the function of GATA1 in red blood cell growth [10].

STIL (SCL/TAL1 interrupting locus)

STIL plays an essential role in red blood cell production [11, 12, 13].

EKLF1 (Erythroid Kruppel-like Factor 1)

EKLF1 is a gene that is necessary for the proper maturation of red blood cells [14].

EKLF participates in the production of adult globin chains [15].

Mutations in this gene are associated with anemia, β-thalassemia, hereditary persistence of fetal hemoglobin (HPFH), and rare In (Lu) blood group [16, 17, 18, 19, 20].

EPO

Erythropoietin (EPO) and its receptor (EPOR) stimulate red blood cell growth and cell division in the bone marrow and the initiation of hemoglobin production [21, 22, 23, 24].

The T allele of SNP rs1617640 in the promoter of the EPO gene is associated with diabetic eye and kidney complications [25].

EPOR

EPOR (Erythropoietin receptor gene) promotes the proliferation of immature red blood cells and survival [26].

Defects in the EPOR may produce erythroleukemia and familial erythrocytosis (an inherited condition characterized by an increased number of red blood cells and an elevated risk of abnormal blood clots) [27, 28].
